ALARM: CLOCK.

Application filed October 14, 1922.

T 0 all whom it may concern:

Be it known that I, PAUL LUX, a citizen of the United States, and a resident of Waterbury, county of New Haven. and State of onnecticut, have invented certain new and useful Improvements in Alarm Clocks, of which the following is a specification.

This invention relates to clocks and more particularly to an alarm clock having improved means for indicating the condition of the alarm producing mechanism.

One object of the invention is to provide an alarm clock having means visible from the front of the dial for indicating whether the alarm mechanism is locked or unlocked.

A further object is to provide a device of the above nature which will be simple, chea" to manufacture, easy to manipulate, and very efficient and durable in use.

With the above and other objects in View, there havebeen illustrated on the accompanying drawing, two forms in which the invention may be conveniently embodied in practice.

Fig. 1 represents a perspective view of an alarm clock to which the first form of the invention has been applied.

Fig. 2 is a perspective view of the in ternal mechanism of the first form of the invention, showing the manner in which the locking and indicating means are mounted in the frames of the clock.

Fig. 3 a front view of the dial of the second illustrated embodiment of the invention.

Fig. 4 is a perspective view of the indicat ing mechanism employed in. the embodiment shown in Fig. 3.

In previous alarm clocks, in order to indicate whether or not the alarm was set to operate, it has been customary to place certain marks or legends on the rim of the casing. These marks or legends. however, were difficult to read, even when the clock was new, and after a short period of use, were often rubbed off or became coated with dirt or rust so as to be entirely illegible.

With the present invention, the above and other disadvantages, have been largely avoided. This has been accomplished by locating the marks or legends as well as the indicator, which cooperates therewith, inside of the clock, in such a position that it Serial No. 594,462.

will be protected from rust or injury due to handling, and yet be in position to be read ily visible from the front of the dial.

Reference will now be had to the drawing, in which like reference numerals denote corresponding parts throughout the several views.

In the first embodiment of the invention, illustrated in Figures 1. and 2, the numeral. 10 designates the casing of the alarm clock, ithin which is located the usual timekeeping mechanism and the mechanism for producing the alarm. not shown. The ala m-producing mechanism preferably includes a bell which is adapted to be rung by a vibratory hammer 11. In order to set the alarm mechanism to ring at any pre-deterrnined time, the usual alarm set. not shown. may be provided on the rear of the casing, said alarm set being connected with a pointer 12. preferably located in front of the dial 1'? upon which a suitable scale of hours 12 is marked.

The casing is provided with the usual front supporting legs 18 and 14, and has a bezel 15 for securely holding a crystal 16 in front of the dial 17. The dial 1'? is provided with the usual hour and minute scale 17 on its periphery. and near the bottom thereof, has the legends Alarm and F ilent. as shown in Fig. 1.

In order to support the dial as well the time-keeping and alarm-producing mechanism of the clock, a pair of parallel plates 18 and 19 are located within the casing. A horizontal shaft 20 is mounted in suitable bearings near the bottom of said plates 18 and 19, and extends a short distance beyond the front and rear of said plates. A pointer 21 is fixed on the front extension of said shaft 20 and is adapted to rotate in front of the legends previously mentioned. The rear extension of the shaft 20. behind the supporting plate 19. provided with an arm 22 having a pin 23 projecting from its end. The pin 23 is adapted to fit within a. slot 24 on the lower end of an alarm shutoff lever pivotally mounted in a manner to be hereinafter more fully described. The end of the shut-oh. lever 25 is provided with a hand-knob 26 adapted to extend outside of the clock through a. suitable slot, not shown, in the back 2"? of the casing 10. This hand-knob 26 is preferably located near the top of the clock so that it will be in a con venient position for easy manipulation.

Adjacent the, hand-knob. 26,. the .lever 25 is providedwith aninclined leg section 28, connected by a vertical section 29 to an upstanding leg section 30, the latterterminating-in'a flat base or pivoting section 31. The lever-basedl is adapted to be held in fric' tional contact with the back 27 of the casing by means of a cone-shaped friction pin 27 secured to said back 27,,in any suitable manner, as by a rivet.

The. lever ,base 31. is provided on one side with a cam lug 31? perpendicular to the lever, base and arranged at an angle to'the, center line of ,the lever. When the lever-25 is rocked totheilefton itspivot, .this cam lug 31 is adapted .to engagetheupper portion. 32 of the vibratory hammer 11, as shown in the dotted, lines in Fig. .1, andin full lines in Fig. 2. The bottom of the lever base 31 is provided with an upstanding leg, which is joined by a straight vertical section 34 to an inclined portion having; the slot 24 previously, mentioned. a, i ..i

In operation, assuming that it is desired to have the alarm ,ring at the pre-deten mined time, for Which-itisset, the shut-off lever 25 will be rotated in aQclock-wise directiQ lv by moving the hand-knob 26 to the right until it reaches the, position, shown in, dotted lines in, Fig, 2. Tl1is,.movement of the shutofflever, will cause-the pin 23 on the end of the arm 22 to rock the shaft 20 and the pointer 21 in front, of the dial 17 will thenhe positioned in frontvof: the Word Alarm-lhiwhen itis desired toprevent the alarm-producing mechanism from. function ing, 'it will onlyIbe necessary toirock the lever 25 in a, counterclockwise v direction by moving the hand-knob 26.,to the left from the dotted tolthe full line position shown in Fig; 2. During this operation,- the camlug 31 will engage the upper portion 320i the vibratory hammer 11 and preventit from strikingthe b ell At fthesame time, the,. pointer 21 inffront of the, dial ,17 will be shifted back to the right, until it comes ope posite the Word .,Silent.? r

Inthe modified form of the invention shownf in Figs, 33nd 4, the extension ofthe shaft 20 in front of t he supporting plate, 18 carries a target 35 preferably comprising. a seirii-circular disc, uponWhiCh are mHVI'kBdH the Words; Silent and Alarm.;v The target Bfnis adapted to rotate behind an open ing 36 in theg dial l7. The opening 36 should preferably begin the shape, of a quarter sector of a circle ofthe same diame-( ter as the ta rget disc 35,sov that only onehalt .of ,said target. ,will be visible through, the dial at'any'onatime.v o Whilefthere haveLbeen disclosed in this specification, two forms which the invention maybeembodied, it is to beiunderstood clock, and, adapted to releasably lock said:

v locking means that these forms are shown for the purpose of illustration only, and that the invention is not .tovbe limited to the specific disclosures but may be modified andembodied in Va rious other forms without departing from its spirit. I11 short, the invention includes all the modifications and ci'nbodiments (zona ing withinthe scope of the following claims. Having thus described the invention, What is claimed as new and for which it is desired .to secure LettersPatent is: i 1. In an alarm clock, a casing. time-keeping and alarm-producing mechanism mount- 1 ed in said casing, means for releasably looking said alarm-producing mechanism. and an indicating pointer in front of the dial of said clock to show whethersaid alarm-producing mechanism is lockedornnlocked. 2.v Inan alarm clock,- a casing containing time-keeping and alarm-producing mecha: nism, and having a dial, a lever located in said casing alocking element on said love! adapted, to releasably lock said. alarm producing mechanism, and-a pointer in front of, said-dial operated by said lever for visually indicating, whether the mechanismis set for Alarmt-or Silent. 1 r t 3; Inan alarm clock, a casing, an alarm mechanism, a shut-off lever located-in said D5 alarm mechanism, a pointer shaft'connected to said levervand adapted to be-rotated thereby, a, pointeron, said shaft located in front of the clockv dial, said pointer, indi-v eating whether the mechanism is set. for alarmor silent.- .i t
